Opis:: Exhaust gases from engines of seagoing ships are the serious problem for environment. That is why the discussion in the matter is very important. One of means to minimise harmful substances emission to earth atmosphere is application of „ecological fuel" — natural gas or nuclear energy for ship propulsion. Natural gas is commonly used in onshore applications but is rarely applied in marine propulsion. Heavy Fuel Oil is the basic brand of fuel used onboard ofseagoing ships. Other kinds of fuel e.g. Diesel Oil or gas Oil are used on smaller ships with limited sailing range. The nuclear energy, due to high costs is used only on few types of warships and some icebreakers. A real means for minimising harmful substances in exhaust gases from ships engines is replacement of Heavy Fuel Oil by Natural gas. Nowadays, heavy oil is commonly used due to technical and logistic abilities and conservative attitude of ship owners. The necessity of improvement in the field of environment protection inclines towards wide application of Natural gas as marine fuel. Application power-plant novel type would break the traditionalism in the shipbuilding and the introduction novel generation ofshipping drives.

Opis:: Investigation on fuelling a dual-fuel compression ignition engine with various fuels, that are unconventional for this type of engine, was carried out for many years in the Department of Internal Combustion Engines and Automobiles in Technical University of Radom. Such fuels as methanol, ethanol and natural gas were applied in the investigation. Recently, the investigation regards application of LPG - a fuel that is very popular in Poland. Within the project No. 4T12D02226 of the Committee of Scientific Research, it was tested, among others, an engine equipped with injection system for diesel fuel pilot dose - a common rail type. As a result of the former investigation, load characteristics of specific energy consumption as well as CO, CO2, nox, HC and smoke emissions data were obtained [1]. In order to analyze variability of fundamental combustion process parameters, histories of the pressure inside combustion chamber have been registered during investigation. Investigation on changes of these parameters in the described engine version is particularly important due to possibility of knocking combustion occurrence that leads to the failure of such engine parts as piston or valves. Changes of these parameters versus engine load for various injection timing of diesel fuel pilot dose were analysed.

Opis:: An idea of using biomass for generating electricity and heat leads to new solutions for power generators, adapted to be supplied with gaseous and liquid biofuels. At present, there is a growing interest in low-power generators. This type of energy production is termed 'scattered energy generation'. It is expected that generating energy in small units situated close to energy consumers may bring about substantial benefits. It is assumed that in a scattered energy generation system, energy will be produced from local fuels, such as broadly understood biomass as a primary component for production of gaseous and liquid biofuels to power low-power energy generators. An adequate amount of biomass must be secured to ensure that biogas can be produced all year round. The easiest way to store highly efficient biomass is to ensile maize and rye as well as grass. The amounts of biogas obtained from these two types of silage are comparable. Using rye as a renewable energy source for production of either bioethanol or biogas is economically viable for at least two reasons: rye grows on poor class soils and rye cultivation technology can be reduced to just nitrogen fertilization. In conclusion, it seems reasonable to generate energy in Poland in scattered energy generation systems from crops grown for this purpose. Currently, gas-powered engines are being in several ways.

Opis:: The results of CFD modelling a dual fuel diesel engine powered with both methanol and diesel fuel is presented in the paper. Modelling was performed with 20 and a 50% energetic share of methanol in the entire dose. The analysis was conducted on both the thermodynamic parameters and exhaust toxicity of dual fuel engine. It was found that the various share of methanol influences the ignition delay of the combustion process and after start of main phase of combustion, the process occurs faster than in case of the diesel engine. It was found that the time of 10-90% burn of the fuel is much shorter than it is in the diesel engine. The dual fuel engine was characterized by higher indicated mean pressure in the whole range of diesel fuel injection timings. While analysing toxic exhaust emission from the dual fuel engine powered with methanol, it was found that the rate of NO formation was significantly higher than from the diesel engine. The combustion process in the dual fuel engine occurs more rapidly than in the conventional diesel engine, which contributes to form areas with high temperature, and in combination with presence of oxygen from the air and oxygen bonded in the methanol, promotes the NO formation. In the case of the dual fuel engine, it was found that soot emission was reduced. The engine running with diesel injection start at 8.5 deg before TDC, the soot emissions were more than twice lower in the dual fuel engine, while the emission of NO was much higher.

Opis:: Dual fuel compression ignition engine can be run on diverse fuels, both gaseous and liquid ones. Alternative fuels to the Diesel oil feature, as a rule, low cetane number and high temperature of self-ignition. Due to this, such fuels can not be ignited spontaneously and require ignition from small dose of the Diesel oil. In the dual fuel system, as the main fuel can be considered a liquid fuels, which can be supplied to the cylinder in form of vapours, or injected be to the suction manifold. Methyl and ethyl alcohols, or their esters, can be counted among future fuels. Such alcohols can be either the main fuels or small additions improving combustion of the Diesel oil. In the paper are presented test results of the SW 680 engine run on methanol and Diesel oil. Methanol was supplied to the suction manifold in form of methanol-air aerosol. Energetic fraction of the methanol amounted to 12-50%, depending on engine load. Performed tests have shown advantageous effect of the methanol on performance of the engine. One confirmed considerable growth of overall efficiency of the engine in area of higher loads (3-6%), reduction of smokiness of exhaust gases achieved as early as with small additives of the methanol (2-3 times), reduction of CO and CO2 emissions, reduction of exhaust gases temperature. Small addition of the methanol affects advantageously on combustion of the Diesel oil, shortening time if its combustion. Addition of the methanol enables maintaining effective power of the engine fuelled traditionally, and even its slight growth. Cost of adaptation to dual fuel supply with alcohol are low, and such type of fuelling can be easy implemented in already operated compression ignition engines.

Opis:: At the moment, there is a growing interest in low-power generating units in dispersed system. The production of energy in small units located in the vicinity of the energy recipients offers considerable benefits. First and foremost, it lowers the cost of energy production and the cost of its transfer and also makes the recipient independent from the domestic supplier. Small cogeneration aggregates will facilitate the use of energy from dispersed renewable resources. Gas self-ignition engines in cogeneration system powered with biofuels can be used in construction industry as ecological sources of heat and electrical energy, limiting the need for fossil fuels. This paper presents the possibility of using alternative fuels for internal combustion engines. It describes the possibility of using liquid biofuels separately or natural gas fuel to power diesel engines in dual fuel system. The conception of supplying low-power generator with diesel engine with natural gas to a dose of liquid biofuels test case. Pointed to the factors determining the desirability of a particular concept. Indicated the modification of the engine power to supply the natural gas generator with a dose of liquid biofuels. New technologies of extracting and using biofuels and alternative fuels are being introduced and developed for generating heat and electric energy. Studies on the use of gas and liquid alternative fuels are directly linked to research on the production of renewable and alternative energy as well as environment protection by minimizing emissions of toxic substances into the atmosphere.

Opis:: The pursuit of reduced greenhouse gas emissions, as well as the increased share of renewable fuels in the overall energy balance has led to a search for alternative energy sources. One of the fuels on which great hopes are set as fuel for engines is biomethane or biogas, whose main component is methane. Biogas can be obtained from different products by using different technologies, so that it has potential as a widelyavailable fuel, which is quite easy to produce. The percentage of methane in biogas depends on the technology for obtaining biogas and ranges from 35% to around 75%. The largest biogas sources can be animal farms, where it is obtained from animal excrement. Another source is sewage treatment plants and rubbish dumps, where substantial quantities of biogas are obtained as a result of natural processes occurring in waste dumping sites or sewage. Biogas can also be acquired from waste obtained from fruit and vegetable processing as well as waste from meat plants. This paper examines the possibility of using biogas as a fuel for diesel engines. In these engines, the combustion of biogas (methane) requires the application of a dual-fuel supply system in which liquid fuel initiating gas fuel selfignition will be injected into the combustion chamber along with methane. The paper also contains example results showing the effect of the methane dose on the course of the combustion process in diesel engines.

Opis:: One of the basic problems concerning dual fuel powering of self-ignition engines is to determine the minimal dose of diesel oil injected into the combustion chamber in order to trigger self-ignition. Most research conducted to date on double-fuel powering self-ignition has been carried out on engines with mechanical injection systems, which does not ensure the possibility of obtaining very small diesel oil doses initiating self-ignition. The original system of fuelling the engine with diesel oil was replaced with a laboratory Common Rail system. The basic parameters of injector operation were controlled by a specially-developed system ensuring continuous choice of parameters of injector operation. The examined engine was fitted with a prototypical system of methane-air fuelling and a system for controlling and adjusting the supplied dose of methane This study presents the results of research aiming at determining the pilot dose injected into the combustion chamber of the engine to ensure the course of combustion in the engine operating under various loads. The results presented in the paper concern tests of a single-cylinder self-ignition engine, HATZ 1B40, operating in a generator adopted for CNG fuelling.

Opis:: Following the modern fuel market, one can notice that prices of liquid petroleum derivatives - petrol and diesel oil - which most often fuel piston internal combustion engines are increasingly higher. Similarly, the price of petroleum-derivative gas (LPG - the liquefied petroleum gas - simply speaking, a mixture of propane and butane) is also growing. Many academic and industrial institutions of science conduct research to determine whether it is possible to replace liquid petroleum-derivative fuels with some other potentially cheaper ones. It would also be beneficial if these new fuels were more "ecological" - so that their combustion products would not be harmful for the environment and if they were produced with the use of plants. Fuel stations commonly offer a fuel for diesel engines which is a mixture of fatty acids methyl esters (FAMEs) from vegetable oils, in Poland for instance from rape seeds. The paper presents a comparison of selected operating parameters of the Hatz 1B40 engine fuelled with mixtures of diesel oil or liquid bio-fuel and natural gas. Indicator diagrams, exhaust gases composition and vibration signals recorded on the engine body were analyzed. The study was conducted on the Hatz 1B40 diesel engine which is used among others in FOGO power generator sets, after replacing the original feeding system by common rail system for liquid fuels and after adding natural gas feeding system.

Opis:: Today, more and more attention is paid to search for alternative fuels, which would be not only environmentally friendly, but also cost-competitive to petroleum fuels. In the recent years much attention is paid to investigations at adaptation of combustion engine to run on bio-fuels. Results of the investigations show, that methyl and ethyl alcohols could belong to one from the most promising and future bio-fuels, being a serious alternative to petroleum fuels. Interest in these fuels comprises such areas as exploration of raw materials to production of the alcohols, development of technology of their production, especially 2nd generation of ethyl alcohol, special fuelling and control systems, design changes of the engines fuelled with alcohols. In the present paper are shown test results of Fiat 1.3 Multipoint engine fuelled in dual fuel system with methanol and gasoline. In this engine one assembled prototype fuel supply system with duplex injectors on each cylinder, to injection of methanol and gasoline. Implemented system enables fuelling with gasoline only, with methanol only, or simultaneously with gasoline and methanol with any fraction of the methanol. Change of fuelling system and change of methanol fraction can be accomplished in course of engine operation. Performed investigations showed advantageous effect of the methanol on toxicity of exhaust gases. One confirmed reduction of emissions of hydrocarbons, nitrogen oxide and carbon dioxide. The biggest changes in the concentration occurred in case of fuelling with the methanol only, and amounted to: 2-3 times reduction of the THC, reduction of NOx with 40-60%. Differences in concentration of NOx increased together with growth of engine load, and hence, they concern such areas of engine operation, where the biggest quantities of the NOx are emitted. In case of dual fuel feeding, effect of reduction of concentration of the components discussed here decreases according to reduced fraction of the methanol. Changes in the emissions discussed here are obtained with maintained engine performance and growth of overall efficiency of the engine. Implemented system eliminates problems of stratification of methanol-gasoline mixture in low temperatures and in presence of water. The system can be adapted to any liquid fuels.

Opis:: Agriculture farms, especially animal farms consume a lot of energy. They also have big potential to produce energy by themselves. The production of biogas and its efficient utilisation could meet the need for fuel and energy. The production of biogas on a farm and its utilisation as a fuel could improve its energetic balance and safe some money. The paper describes the possible way of utilisation of upgraded manure biogas as a fuel for compression ignition engine, which is adopted for dual fuelling. The engine is going to be fuelled with vegetable oil ester and biogas produced directly on animal farm. Some calculation of fuel consumption of both fuels and analysis of possible changes of combustion process for dual fuelling mode are presented. There is also described the concept of adaptation of CI engine for agriculture tractor to dual fuelling with vegetable oil ester and biogas. In Poland, there are about 1300 caw farms, 3000 pig farms and about 3500 chicken farms. Taking into account that the production of biogas is efficient and give some profit for minimum 100 caws, 500 pigs or 5000 chickens in the farm, there is together about 7800 farms where production of biogas could be profitable [2]. At the end of 2009 there were only 126 installation for biogas production and they produce 70.88 MW of energy. Biogas is one of the most promising sources of renewable energy because the efficiency of conversion of biomass into fuel is relatively high.

Opis:: Degradation of the environment is nowadays believed to be the most alarming problem that needs to be solved. Global warming and environmental pollution are predicted to cause a catastrophic chain reaction leading to species extinction, mass emigration due to rising sea levels and global crisis. The only solution suggested by international organizations is the immediate reduction of greenhouse gases and other harmful substances. Marine transportation harmful substances into the atmosphere are recognized to be a significant source of global atmospheric pollution. Despite the high efficiency of marine diesel engines, their impact on the environment is considerable. Due to environmentally friendly policies, modern engines concerns about not only efficiency but also mainly about s aspects. This article analyses and compares marine s exhaust gases reduction methods. Especially the most harmful substances emitted by ships were taken into consideration. The article presents the most crucial law regulations of harmful substances to the atmosphere, pointing at actual and possible future implementations. The most complex methods allowing meeting the latest limits were presented. Pros and cons of available control methods were thoroughly described and methods were compared. The most adequate methods form the effectiveness and economical point of view was pointed out.

Opis:: The traditional use of fossil-based fuels is now widely considered unsustainable because of depleting their natural resources. Potential substitutes of fossil fuels are oils of renewable origin such as various vegetable and non-edible oils. The aim of using these oils or their methyl esters (biodiesel) is to establish and maintain a balance between agriculture, economy and environment protection. However, realizing the increasing demand of raw materials currently used can be achieved not only by increasing the production area but also by introducing new materials or technologies. The article presents and evaluates modern raw fuel components that are currently being investigated. Furthermore, the article deals with the dual fuel combustion technology in detail, with which the processed fuels are becoming available for use in Compression Ignition (CI) engines, where conventional blending is difficult or their use exclusively in diesel engines is economically unjustified. In case of dual fuel engine systems, the primary fuel, such as (wet)ethanol, methanol, LPG, H2 etc. is injected into the intake manifold of the engine and the premixed mixture simultaneously produced is ignited by the pilot diesel fuel as secondary fuel injected directly into the engine cylinder. This technology can significantly reduce exhaust emissions and can slightly increase engine efficiency. The achievements in this field and recently obtained results by the author and his research group are also presented. Exhaust emissions, performance and combustion characteristics were measured and analyzed with respect to several operating parameters as follows: premixed ratio (rp), pilot timing and engine load.

Opis:: Results presented in the article regard the research on a turbocharged dual-fuel CI engine operating on propane. The research indicated that such engine might operate even if 70% of the standard fuel energy is replaced by propane. The research indicated that at such high share of the gaseous fuel, there is necessary to adjust diesel fuel injection parameters but it is important that there is no need to change the engine structure. Injection parameters may be adjusted in a wide range due to the modern fuelling system of the common rail type. The investigated engine was equipped with such system. Adjustments regarding the fuel charge division, fuel charge quantities, and injection timing enabled to influence combustion in such way to obtain its specific parameters, i.e. maximum combustion pressure, rate of pressure rise, maximum pressure, and the burn out ratio similar to those obtained for diesel fuel operation. The obtained results were presented in form of adjustment characteristics of the injection timing of diesel fuel pilot dose for a few chosen values of the boost pressure as well as injection timing of the main dose. The investigations were carried out for three values of the boost pressure, i.e. 200; 400 and 600 [mbar] but also for the naturally aspirated version. Injection timing of the first dose varied in a broad range and depended on the boost pressure. Injection timing of the second dose varied in a narrower range, mainly due to considerable changes in the combustion process. The obtained results answered a number of questions regarding the strategy of selection of diesel fuel injection parameters taking into consideration engine performances as well as combustion at a high share of the gaseous fuel.

Opis:: Biogas is among the fuels whose significance in the general energy balance will increase. These results from the fact that it may be produced from various kinds of waste materials, and it is therefore considered a renewable fuel of the second generation. Because of its properties, biogas may be used directly to power spark-ignition engines. Nonetheless, numerous tests are underway involving the possibility of using biogas to power compression-ignition engines. In order to use biogas, whose main combustible component is methane, in compression-ignition engines, it is necessary to use a dual fuel power supply system. With such a system supplying power to the engine, the gas and air mixture in the cylinder is ignited by a small dose of liquid fuel. This paper presents a fragment of the research on the use of biogas with a varying chemical composition for powering compression-ignition engines. The described tests were conducted using a one-cylinder compressionignition engine mounted on an engine test stand. The fuel gas consisted of a mixture of natural gas and carbon dioxide; the share of each individual component was regulated from the station, which controlled the operation of the whole test stand. The developed control system also enabled the adjustment of the operating parameters of the engine test stand and the parameters of the injection of liquid fuel, such as the injection pressure, the timing angle of injection and the size of the dose. The results presented in the paper show the impact of the individual control parameters of the engine on the value of the engine’s torque and the amount of toxic compounds in the exhaust fumes.
